RALPH C. SIMMONS, OF BEVERLY, MASSACHUSETT$, ASSIGNOR TO UNITED SHOE IIIACHINERY CORPORATION, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

Application filed December 8, 1919.

To all 10710-722. it may concern:

Be it known that I, RALPH C. SIMMONS,

a citizen of the United'Stat-es, residing at Beverly, in the county of Essex and State or other suitable material are assembled to form heels.

Automatic heel building machines have heretofore been proposed but have not met with the commercial and practical success desired by reason of the difliculty encountered in maintaining control of the individual lifts, complication in construction and consequent slowness of operation of the ma chines, difficulty in pasting and in operating upon the pasted lifts. In a prior application, Serial No. 81AO5, filed March 1, 1916, a heel building machine was shown and described which, to a large extent, overcame the previously existing practical difficulties mentioned. In the machine of that application a series of heel lifts is taken from a series of stacks and simultaneously placed upon lift supports arranged in the plane of the bottom of the stack, and assembling means thereafter moves the individual lifts from the supports onto other partially" formed heel piles by movement of the'jassembling means the distance of separation of the stacks after each supply of heel lifts. This machine has given satisfactory practical results and the present invention is a further development of this general type of machine. i i I As in the machine of the prior application, the present invention provides for re moving a series of heel lifts from a corresponding series of' stacks and simultaneously delivering the lifts to a support, which, however, is not in the plane of the bottoms of the stacks or magazines but preferably a sufficient distance below such plane that I-IEEL-BUILDING MACHINE. 1

Serial No. 343,381.

the heel lifts may be delivereddirectly upon.

incomplete piles of heel lifts previously formed. An important feature of the invention, therefore, consistsof a heel lift support normally in fixed relation to the stacks, below the bottom, and at one side thereof, and to which a series of heel lifts is delivered simultaneously.

In the practical embodiment of this feature, magazines are provided to hold a series of stacks of heel lifts, and the lift support is arranged to extend past and adjacent to the magazines below the plane of their bot toms. The heel lifts are moved from the y magazines," and when they are to be supplied with paste or an adhesive, they are passed over pasting means, and thensimultaneously delivered to the lift support, all except the first lift of the series being deQ posited upon'a partially formed heel pile.

' It is desirable that the lifts in the partially formed heel piles be retained in substantially their co-related superposed positions as they are moved inte'rmit tently along the support notwithstanding the fact that in practice, at le 'ast, it is usual to gradually diminish the size of the lifts upwardly of-the pile. feature of the invention therefore consists of guides which converge upwardly from the lift support and graduallyincrease in height towards the point of delivery of the completed pile of heel lifts. V

The heel lifts are removed from the maga-h zines or stacks by pushers to which the lifts are liable to adhere on account of the film Another important of paste that lodges between the pushers vent the lifts following the pushersas they retreat. This feature of the invention may be carried into practical effect by means of lifters or stops which drop behind the lifts when they reach delivery position.

It is important to stop the machine should tending side guides at different points longitudinally of the machine;

The main frame of the machine may be suitably constructed to sustain the various elements of the machine, and in the present instance comprises the end members 10 between which extend the tie beams or braces 11. Connected to the main frame by the joints or hinges 13, is an auxiliary frame 14. The auxiliary frame 14 consists essentially of a plate or casting and a scriesof parallel partitions 15', Figs. 1 and 3, extendingforward- 1y from the rear plate or casting 16 of the auxiliary frame to form passage ways 17, in which operate the lift feedingmcans orpushcrs, will more fully appear.

In the passage-ways 17 between the partitions 15 is mounted a series of heel lift magazines, Figs. 1 and 2, in which are supported stacks of heel lifts. When the piles of lifts to be formed are to be built from heel lifts of uniform thickness throughout, the magazine for supporting the stacks of heel lifts may be substantially as fully shown and described in the prior application, and sub stantially as indicated in Figs. 1, 2 and 6, wherein the magazines for this character of lifts consist of the opposed walls 18 and 19 in which the heel lifts 20 may be stacked and by which they may be guided to the delivery or feed point at the bottom portion of the magazines To accommodate the 18 and 19 are preferably adjustable. relativev ly, as indicated in Fig. 2, by the adjusting bolts 21 passing through suitable slots in the portion 22 rising from the auxiliary frame.

The lowermost heel liftsin the series of magazines thus provided lie upon a rest 23 in the path of the feeding means or pushers, to be described. The rest23 preferably consists of a grid either made up of a plurality of bars, as pointed out in the priorapplication, or formed as a grooved table, the latter being the form of rest herein illustrated. The grooved table extends from near .the rear to a point near the front of the passage-ways 17 between the partitions 15, the sharpened edges of the grooved construction acting to resist angular vmovement ofthe lifts as they slide along the grid towards delivery position to the depressed lift support, as will later appear, and also acting'in a measure to prevent the accumulation of paste which is appliedto the surface of the heel lifts as they are moved from the magazines toward delivering position.

Extending longitudinally of the machine in front'of the line of magazines, is a paste roll shaft 24: which 1s provlded with a series of paste rolls 25, one projecting into each of the passage-ways 17 in front of each of the magazines, the. purpose being to provide means for delivering paste to the surface of the series of heel lifts as they are moved from the magazines, towardsdelivery position, to the depressedheel lift support In the present instance of the invention the table or rest 23 formed as hereinbefore described, is interrupted at the point where the paste rolls 25 are located to, permit the surface of the paste rolls to project upwardly into the line of feed of the lifts.

The paste rolls 25 extend into the paste trough 26 which contains a sufficient quantity of paste to supply the rolls; The trough 26 may be conveniently supported either at its end or upon longitudinally extending beam members 27 and 28, Figsj l: and 6, which, together, I form a chamber 29 for maintaining the paste or adhesive in sufliciently liquid form for ready application to the heel lifts.

Where the heel lifts are .to be assembled in piles soon after the application of paste thereto, it is desirable to employ a quick drying paste or adhesive and in order to maintain such quick drying paste or adhesive in proper liquid form, its temperature is kept sufficiently high by some form of heating means. In the present instance of the invention the chamber 29 formed of the members 27 and 28 has extending longitudinally thereof the heating pipes 30, Figs. 4 and 6, which may be connected to a suitable source f heat supply as, vi for instance, :-a

Pivotally mounted on the plate 52 at 54 is the heel lift depressing means which consists of a plate 55, preferably trough-shaped, to enclose between its upturned side flan'ges'the plate 52. A spring 56 normally acts upon the magazine end of the plate 55 to depress that end and an adjusting screw or stop 57 serves to limit the action of the spring. In order to guide the bottoinmost liftunder the plate 55 and into intimate contact with the paste roll, the plate has extending rearwardly therefrom towards the magazine, the curved resilient fingers 58, Fig.6, the construction being such that as the lowermost lift of the stack is moved towards the heel lift support, it encounters the resilient and curved fingers 58 and it is guided by them downwardly onto the cooperating paste roll and held against the paste roll by the plate as the heel lift moves to delivery position. The front end portion 59 of the plate 55 may be sli htly downturned to hold the heel lift firmly upon the rest 23 as it is moved over the top of the side guide 47 and under a lifter or finger, to be presently described. The bracket 51 is adjustably mounted relative to the magazine by means of the bolts 60 and 61, which pass through slots in the bracket, as indicated in Fig. 6.

It is appropriate at this time to describe the heel lift feeding means and cooperating parts. Mounted in suitable bearings in the machine frame, is the main or drive shaft 62, Figs. 2 and 8, having splined thereon one member of a clutch 68. The clutch 63 may be of any usual type well known in the art. Loosely mounted upon the shaft 62 is the pulley 64 which may be continuously driven from an appropriate source of power such, for instance, as a belt connection with a line shaft. The other member of the clutch is connected to or formed as part of the pulley 64, the construction being such that when the clutch members are disengaged, the drive shaft 62 will remain at rest while the pulley 64 will continue to rotate, but when the clutch members are thrown into engagement, as will later appear, the shaft 62 will rotate in unison with the pulley 64.

Hereinbefore mention has been made of the fact that a quick drying paste is preferably employed and in such event that the paste rolls or roll should be continuously driven, even though the machine itself may be at rest. This continuous rotation of the paste roll is accomplished in the present instance of the invention by a sprocket chain 65, Fig. 2, connected to a sprocket 66 on the paste roll shaft 24, and another sprocket67 on the shaft 68 supported by a suitable bracket 69, as best indicated in Figs. 2 and 3. The shaft 68 has secured thereto a gear 70 which is operatively engaged with a gear 71 connected to and operating with the con tinuously driven pulley 64, the construction being such that as long as the pulley 64 continues to rotate, the paste roll shaft 24 will continue in operation. v

Mounted for rotative movement in the end frame members ,10 of the machine and appropriately supported is the cam shaft 72, Figs. 3 and 4, which is driven from the main shaft 62 through a train of gearing 7 3 and 74, the gear 7 3 being secured to the shaft 62, and the gear 74 to the cam shaft 72.

The cam shaft 72 carries near its end 0pposite the gear 74, a cam member 75, and in the faces of the gear 74 and the cam member 75 are formed similar cam grooves 76, as indicated in Figs. 2 and 4. The cam grooves 76 in the gear 7 4 and cam member 7 5, engage respectively the rolls 77 connected respectively to the arms 78, one adjacent each end of the machine fra1ne, which arms are pivoted at their lower ends at 79 for rocking movement under the operative influence of the cam grooves 7 6 and the rolls'77. The rocking arms 78 are connected at their upper ends by links 80 to a slide or pusher actuating means 81, which, in the present instance of the invention, is mounted for reciprocating moveme-nttowards and from the front of the machine, in the guideways 82, Fig. 4, formed on the machine frame. I y

- The slide 81 has connected thereto a number of pushers for pushing the lowermost heel lifts from the several'stacks of heels and delivering them over the guideway 47 to the heel lift support below, or to other partially formed heel piles. The connection between the pushers and the slide 81 may be variously contrived, but in the present instance the slide 81 is provided with a'series of pins 83 which are adapted to register with complemental holes formed in pushers 84, :Figs. 3 and 4. The pushers 84 are preferably formed as plates, for convenience of manufacture and effectiveness in operation, and may be readily connected to or detached from the slide 81 by simply disengaging the pushers from the pins 83.

When the machine is in operation, the slide 81 is reciprocated in its guides 82 and actuates the series of pushers 84 which are connected thereto, and these, in turn, move a series of lifts-equal to the number that, are to appear in any complete heel pile, and deliver them to the depressed heel lift.support or other partially formed pilesx Manifestly, should any pusher fail to deliver a heel lift, the corresponding heel pile will be imperfect and a continuance of non-delivery of a heel lift is apt'to produce quantities of heel. piles of unsatisfactory heights. The. present invention, therefore, aims topro vide'mea-ns for stopping the machine in case of the non delivery of any one of the heellifts of the series. Extending between the 106 on the bell crank 109, the spring 116 further asserts itself and rocks the shaft 102 in the opposite direction and, perforce, moves the feeler to the left, Fig. 13. If, at the time, one of the stop lingers 99 is in the path of movement of the feeler 100 and its movement to its dotted line position, inclicated in Figs. 4 and 6, is obstructed, the shoulder 124 of the catch 123 will remain in the path of the lug 1250f the slide 81 and be engaged thereby as the slide moves rearwardly. As hereinbefore stated, the lowered position of any one of the stops 99 indicates the absence of a heel lift and, consequently, imperfect delivery of the required number of lifts to the lift support. Consequently, when the catch is engaged by the lug 1.25 of the slide, as the latter moves rearwardly, it moves the rod 117 along with it and advantage is taken of this movement to effect stopping of the machine.

The splined clutch member carried by the driving shaft 62 is under control of a yoke 131 having a hub portion 132, Fig. 13, by which it is mounted for rocking movement on the machine frame. The yoke 131 is normally under the influence of a spring 133 acting to disengage the clutch mem bers. A stop rod 134, Fig. 13, is mounted in suitable bearings 135, 2, and carries at its rear end portion a clutch actuating member 136, Fig. 13. Extending upwardly from the stop rod 134 is a hand lever 137 by means of which the stop rod 134 may be rocked to move the yoke 131 against the tension of its spring and engage the clutch members. The lever 137 is connected at its upper end at 133 to a hand piece 139 which extends longitudinally in front of the machine, and is pivotally connected at its upper end at 140 to a lever 141 pivoted at 142, the construction being such that by movement of the'hand piece 139 by the attendant at any point in front of the machine, the stop rod 134 may be rocked to start the machine or, as will later appear, to stop it.

Mounted in suitable bearings 144, is the latch rod 145, Fig. 13. A spring 146 interposed between the bearing 144'and the collar 14? on the latch rod, normally tends to dcress the latch rod to carry its lower end into the path of movement of the yoke 131 when the latter is moved to engage the clutch members and to maintain the clutch members in operative relation againstthe. tension of the yoke actuating spring 133.

The latch rod 145 at its upper end portion carries a transversely extending pin 149, Fig. 12, which straddles the upper bifurcated end of the rod. Secured to the rod 117 is the trip finger 150, Fig. 12, having an upwardly inclined surface 151 which, when the rod 117 is moved to the left, Fig.

13 by engagement of the gravity catch with the lug 125 of the slide, is adapted to be moved under the pin 149 and lift the latch rod, thereby carrying itslower end 148 from the path of movement of the yoke 131 to permitthe spring 133 to disengage the clutch members and, as he'reinbefore noted, thereby effect stoppage of the machine.

The stop rod 134 has secured thereto an upwardly extending member 152, Fig. 13, the upper-end portion of which is provide-d with a cam surface 153 adapted to engage a roll 154 on the latch rod 145, the construction being such that when the machine stopped by failure" to feed one of the heel lifts, as hereinbefore described, the stop rod" 134 will be rotated or oscillated through the effort exerted upon the member 136 by the yoke, as it moves in response to its'actuating spring 133, and the latch rod will be maintained in its upper or inoperativeposit'ion relative to the yoke. hen the machine is to be started by hand, the stop rod 134' is rocked to engage the clutch members and coincidentally therewith to remove the cam 153 frombeneath the roll 154 and thereby permit the lower end of the latch rod to lock the yoke with the clutch members in operative relation and, conversely, when the rod 134 is rocked through the hand lever 13"- to stop the machine by hand,- the cam member 153 again rides under the roll 154 of the latch rod and removes the end 148 of the latch rod from the path of moven'ient of the yoke. The stop rod 145 may be provided with a stop 155, Fig. 13, for limiting its downward movement in response to its spring 146. T

\Vhen the machine has 'beenstopped by failure to feed one of the heel lifts to the lift support, the attendant'will remedy the defect in the feed and remove the'stop 99 from the path of the feeler, whereupon the gravity catch 123 willdrop and the parts resume their position, as indicated in' Fig. 13.

The assembling mechanism or conveyor for intermittently moving the row of heel lifts along the uninterrupted lift support, comprises a chain or conveyor 156, Fig. 1, which is provided with a series of fingers 157 suitably spaced apart to accommodatebetween adjacent fingers the heel lifts which are delivered to the lift support.

Mounted at opposite, ends of the machine frame are the sprocket wheels 159 over which the chain or conveyor 156 passes and by which it is given its directional movement. The lift advancing fingers 157 extend outwardly from the chain or conveyor 156 and through a central opening 160 formed longitudinally of the'lift support,

The conveyor or chain 156-; is given astepe by-step. or. intermittent movement for each, feed movement of; the series of heel lifts, and this may be. effected in any suitable manner. Inasmuch, however, as. the fingers 157, whicheffect the advance-of; the heel lifts along the heel; lift. support, are substantially nonryielding, means are provided? to stop. the. machine. in case.- of; undue. obstruction. to any of thevi-ntermittent' movements of the conveyor or chain.

The teeth of i the ratchet are so spaced that actuation of one tooth. will move the lift assembling fin-- gens or conveyor through a space equal to that hetweencorresponding points of adja cent. lift magazines, and the mechanism is so timed that the fingers stop in their intermittent movement between the magazines there. by permitting the pusher-s which are advanced; at this. time in the cycle of the ma: chine. operation, to deposit the row of lifts magazines upon the lift In order to stop the machine upon undue obstruction to the movement of the assembling mechanism or conveyor, the rod 166is provided with-a notch 180, Fig. 15, having beveled. side portion and engaged by a catch 1.81 having a correspondingly beveled portionv 182. :In the present instance, the catch 181 is formed on a plunger. 183 mounted in a recess in the Upper end of the arm 1.70. The catch 181' isnormally held in engagement with the notch 180 on the thereby lifting the latch and, perforce, the

plunger inthe endof the arm 170.

A toothed segment 187, Fig. 15, is secured to the rocker arm 1 1-1 which, as hereinbefore described, is connected to the stop rod 134. The upper end of. the plunger .183 is vided with a tooth 18 8 which, when the plunger is moved outwardly, due to obstruction to the. movement of the rod 16.6 to the left, Fig. 15., engages, the toothed segment 187 and, perforce, causes movement of the. rocker 141 to the left, Fig. 14, thereby rocking. the stop rod 134 and stopping the machine. Thus, should; the assembling means. meet with any undue or unusual re- Sistance to its intermittent movements, the mechanism is such that the machine may be. automatically stopped without, dangerof breakage of parts.

pro v invention, the heel lifts are supplied with paste as they are moved from the magzn zines to the lift support, the lifts are;

liable to stick to the pushers as the latter retract, and the invention contemplates means for overcomingthis' defective action. In the the present instance, the lifters ordetectors, are utilized as a means for preventing the retracting movement of the heel lifts with the pushers are eachprovided with. a slot 1890,. Figs; 10 and ll, extending from the pushingiorlead}. ing edge ofthe pushers inwardly or leng h. tudinally of the pushers, into. which the lowerend portions: 91 of the hitters may drop when, as indicated; in Fig. 1;(D,.theli-ftshave been moved to their delivering position. O'n retraction of" the pushersi the lifters engage. the edge of the lifts, should any stick to the pushers; and detach them from; the pushers as the latter move back, thus insuring the delivery of an e-ntire now of littts' notwithstanding: any adhesion between the heel lifts and the pusher-s,

Inasmuch as difierent sizes of heel lifts may be treated in the machine and; corresponding adjustments of the side guides: 4!? and 4-8 are provided for that purpose, as

hereinbefore indicated, the lifters 87' are similarly provided each with a slot SQi-pea. mitt-ring adjustment of the lifters to accommodate heel. li fts' of different sizes.

Inasmuch as the lowermost heel, lift is to be removed from the: several? stacksv (le livered to the heel lift support, it is impor-.

tant that the lowermostli ffi shallliefiat and in proper feeding position on the rest: in

front of the feeding means: or pusher Where the heel piles are. to be formech of wedgeshaped heel lifts,- however,- theiwei'ght of the superposedlifts is liable to: upward ly tilt the thin edge of thedowermost lift. Should this occur the lowermost lift will notbe in proper position to be removed 't'roin the magazine because: the upwardly til-ted thinorbreast edge wilhproject above the lower adjacent edge of the: magazine and obstruct the feeding movement and the.

pusher will likewise fail to properly engage the lift. The present invention there:

fore providesmeans for insuring. proper" presentation of the lowermost lift ofa stack of 'wedgeshaped lift'stothe pusher or feeds.

i ng device. This :ispreferably accomplishedi by distributing the weight. of the superposed heel-lifts frontwardly or towards the thin breast edgeof? the lowermost lift/when. it is: in feeding position by relative move ment of the lowermost lift: in a= rearward:

Adjacent to. the delivery portion of the magazine means-.m'ay be providerl for insur ing correct movement'- of the lowermostliftto feedin g position after it? leaves thei stem. This is: eifect'ed 'bythe breast incl ihes 19 2 hereinheforedescribed': and the guides 2 02 which qua-y bear upon the c on-touaor curved rear portion of the-heel lifts las the visucces sively move-tofeeding position; To insure" that the wedge-shaped heel lifts-anew; not be laterally, displaced i or be turned! in the plane of the lifts'asithey approach feeding pos geously employed, one at. each side of the inclines .192, Fig. 16. Thus as the wedgeshapedlift approaches feeding position it is moved rearwardly thereby transferring the weight of superposed lift frontwardly upon itself andtowards the thin breast edge,

and as the lift passes from control of the" correct relation of the lifts before they pass to the nailing or fastening mechanism. In

the present instance the alining means comprises a series of's'pring fingers 205, Figs. 3 and 9. These are preferably supported by one of the side guides,'-as 48, andact upon the heel piles as they are moved past to press yieldingly upon one side of the heel piles and-cause them'toconform to the incline or' surface of the opposite guide 4?. The spring fingers separately act upon'the heel pile at different points in itsheight and just prior'to delivery of a pile to the nailing mechanism.

- It is proposed in the present heel building machine to secure the lifts of each pile in their assembled and-alined relation, and

i to complete the illustration in this respect a suitable heel nailing mechanism is shown,

butas its detailsform no essential part of the present invention it is not herein de-- scribed. If desired the nailing mechanism may be the same as that shown and described inthe mentioned.
